III. INSTALLATION
(Jumpers)
Several hardware settings are made through the use of jumper caps to connect jumper
pins (JP) on the motherboard. See "Map of the Motherboard" on page 4 for locations of jumpers. The jumper settings will be described numerically such as [----],
[1-2], [2-3] for no connection, connect pins 1&2, and connect pins 2&3 respecor on the left
when
tively. Pin 1 for our motherboards is always on top
holding the motherboard with the keyboard connector away from yourself. A "1" is
written besides pin 1 on jumpers with three pins. The jumpers will also be shown
graphically such as
to connect pins 1&2 and
to connect pins 2&3.
Jumpers with two pins will be shown as
for Short (On) and
for Open
(Off). For manufacturing simplicity, the jumpers may be sharing pins from other
groups. Use the diagrams in this manual instead of following the pin layout on the
board. Settings with two jumper numbers require that both jumpers be moved together. To connect the pins, simply place a plastic jumper cap over the two pins as
diagramed.

WARNING: Computer motheboards and components contain very delicate
Integrated Circuit (IC) chips. To protect the motherboard and other components against damage from static electricity, you should follow some precautions whenever you work on your computer.
1. Unplug your computer when working on the inside.
2. Hold components by the edges and try not to touch the IC chips, leads, or
circuitry.
3. Use a grounded wrist strap before handling computer components.
4. Place components on a grounded antistatic pad or on the bag that came with
the component whenever the components are separated from the system.

Jumper Settings
1. Memory Cacheable Size (CBSIZE)
The default of 64MB uses only the onboard TAG SRAM which allows cacheable
memory up to 64MB. If you install DRAM above 64MB and wish to allow
cacheable memory above 64MB, you need to install a TAG SRAM upgrade and
set this jumper to 512MB. See this section for “TAG SRAM Upgrade.”

5. CPU External (BUS) Frequency Selection (FS1, FS2)
These jumpers tells the clock generator what frequency to send to the CPU.
These allow the selection of the CPU’s External frequency (or BUS Clock). The
BUS Clock times the BUS Ratio equals the CPU's Internal frequency (the advertised CPU speed).
6. CPU to BUS Frequency Ratio (BF0, BF1)
These jumpers set the frequency ratio between the Internal frequency of the
CPU and the External frequency (called the BUS Clock) within the CPU. These
must be set together with the above jumpers CPU External (BUS) Frequency

2. System Memory (DRAM & SRAM)
This motherboard supports six 72-pin SIMMs of 4MB, 8MB, 16MB, 32MB, or
64MB to form a memory size between 8MB to 256MB. The DRAM can be either
60ns or 70ns Fast Page Mode (Asymmetric or Symmetric) or EDO. To support
ECC, you must use true (opposed to phantom parity generated by logic chips) 36-bit
parity-type DRAM (e.g. 8 chips + 4 parity chips) in pairs for all modules. Mixing
32-bit non-parity DRAM (e.g. 8 chips) and 36-bit DRAM (e.g. 12 chips) will work
minus the ECC feature.
Install memory in any or all of the banks in any combination as follows:

3. Central Processing Unit (CPU)
The motherboard provides a 321-pin ZIF Socket 7 that is backwards compatible
with ZIF Socket 5 processors. The CPU that came with the motherboard should
have a fan attached to it to prevent overheating. If this is not the case then purchase
a fan before you turn on your system. Apply thermal jelly to the CPU top and then
install the fan onto the CPU.
WARNING: Without a fan circulating air on the CPU and heat sinks, the
CPU and/or heat sinks can overheat and cause damage to both the CPU and the
motherboard. (See "CPU Cooling Fan Connector” at the end of this section.)
III. INSTALLATION
(CPU)
To install a CPU, first turn off your system and remove its cover. Locate the ZIF
socket and open it by first pulling the lever sideways away from the socket then
upwards to a 90-degree right angle. Insert the CPU with the correct orientation as
shown. Use the notched corner of the CPU with the white dot as your guide. The
white dot should point towards the end the of the lever. Notice that there is a blank
area where one hole is missing from that corner of the square array of pin holes and
a "1" printed on the motherboard next to that corner. Because the CPU has a corner
pin for three of the four corners, the CPU will only fit in the one orientation as
shown. The picture is for reference only; you should have a CPU fan that will cover
the face of the CPU. With the added weight of the CPU fan, no force is required to
insert the CPU. Once completely inserted, hold down on the fan and close the
socket's lever.
IMPORTANT: You must set jumpers for "CPU to BUS Frequency Ratio" and
jumpers for "BUS Frequency Selection" depending on the CPU that you install.

4. Expansion Cards
WARNING: Make sure that you unplug your power supply when adding or
removing expansion cards or other system components. Failure to do so may
cause severe damage to both your motherboard and expansion cards.
First read your expansion card documentation on any hardware and
software settings that may be required to setup your specific card.
NOTE: PCI Slot 4 has a MediaBus extension 2.0 which allows the installation of a
PCI card or a MediaBus card (optional multifunctional card) but not both.

9.
Read the documentation for your expansion card.
Set any necessary jumpers on your expansion card.
Remove your computer system's cover.
Remove the bracket on the slot you intend to use. Keep the bracket for possible future use.
Carefully align the card’s connectors and press firmly.
Secure the card on the slot with the screw you removed in step 4.
Replace the computer system's cover.
Setup the BIOS if necessary (such as "IRQ xx Used By ISA: Yes" in PNP AND
PCI SETUP)
Install the necessary software drivers for your expansion card.
Assigning IRQs for Expansion Cards
Some expansion cards need to use an IRQ to operate. Generally an IRQ must be
exclusively assigned to one use. In an standard design there are 16 IRQs available
but most of them are already in use by parts of the system which leaves 6 free for
expansion cards.
16
ASUS P/I-P55T2P4S User’s Manual
III. INSTALLATION
Both ISA and PCI expansion cards may need to use IRQs. System IRQs are available to cards installed in the ISA expansion bus first, and any remaining IRQs are
then used by PCI cards. Currently, there are two types of ISA cards. The original
ISA expansion card design, now referred to as “Legacy” ISA cards, requires that
you configure the card’s jumpers manually and then install it in any available slot on
the ISA bus. You may use Microsoft's Diagnostic (MSD.EXE) utility included in
the Windows directory to see a map of your used and free IRQs. For Windows 95
users, the "Control Panel" icon in "My Computer," contains a "System" icon which
gives you a "Device Manager" tab. Double clicking on a specific device give you
"Resources" tab which shows the Interrupt number and address. Make sure that no
two devices use the same IRQs or your computer will experience problems when
those two devices are in use at the same time.
III. INSTALLATION
(DMA Channels)
To simplify this process this motherboard has complied with the Plug and Play (PNP)
specification which was developed to allow automatic system configuration whenever a PNP-compliant card is added to the system. For PNP cards, IRQs are assigned automatically from those available.
If the system has both Legacy and PNP ISA cards installed, IRQs are
assigned to PNP cards from those not used by Legacy cards. The PCI and PNP
configuration of the BIOS setup utility can be used to indicate which IRQs are being
used by Legacy cards. For older Legacy cards that does not work with the BIOS,
you can contact your vendor for an ISA Configuration Utility.
An IRQ number is automatically assigned to PCI expansion cards after those used
by Legacy and PNP ISA cards. In the PCI bus design, the BIOS automatically
assigns an IRQ to a PCI slot that has a card in it that requires an IRQ. To install a
PCI card, you need to set something called the INT (interrupt) assignment. Since all
the PCI slots on this motherboard use an INTA #, be sure that the jumpers on your
PCI cards are set to INT A.
Assigning DMA Channels for ISA Cards
Some ISA cards, both Legacy and PNP may also need to use a DMA (Direct Memory
Access) channel. DMA assignments for this motherboard are handled the same way
as the IRQ assignment process described above. You can select a DMA channel in
the PCI and PNP configuration section of the BIOS Setup utility.
IMPORTANT: Choose "Yes" for those IRQ's and DMA's you wish to reserve
for Legacy (Non-PnP) ISA expansion cards in “IRQ xx Used By ISA” and “DMA
x Used By ISA” of the PNP and PCI Setup in the BIOS SOFTWARE section,
otherwise conflicts may occur.

Hard Disk Drives
This field records the specifications for all non-SCSI hard disk drives installed in
your system. The onboard PCI IDE connectors provide Primary and Secondary
channels for connecting up to four IDE hard disks or other IDE devices. Each channel can support up to two hard disks; the first of which is the “master” and the
second is the “slave”.
Specifications for SCSI hard disks need not to be entered here since they operate
using device drivers and are not supported by any the BIOS. If you install other
vendor’s SCSI controller card, please refer to their respective documentations on
how to install the required SCSI drivers.

For IDE hard disk drive setup, you can:
• Use the Auto setting for detection during bootup.
• Use the IDE HDD AUTO DETECTION in the main menu to automatically
enter the drive specifications.
• Enter the specifications yourself manually by using the “User” option.
The entries for specifying the hard disk type include CYLS (number of cylinders),
HEAD (number of read/write heads), PRECOMP (write precompensation), LANDZ
(landing zone), SECTOR (number of sectors) and MODE. The SIZE field automatically adjusts according to the configuration you specify. The documentation
that comes with your hard disk should provide you with the information regarding
the drive specifications.
The MODE entry is for IDE hard disks only, and can be ignored for MFM and ESDI
drives. This entry provides three options: Normal, Large, LBA, or Auto (see below). Set MODE to the Normal for IDE hard disk drives smaller than 528MB; set
it to LBA for drives over 528MB that support Logical Block Addressing (LBA) to
allow larger IDE hard disks; set it to Large for drives over 528MB that do not support LBA. Large type of drive can only be used with MS-DOS and is very uncommon. Most IDE drives over 528MB support the LBA mode.

Auto detection of hard disks on bootup
For each field: Primary Master, Primary Slave, Secondary Master, and Secondary
Slave, you can select Auto under the TYPE and MODE fields. This will enable auto
detection of your IDE drives during bootup. This will allow you to change your
hard drives (with the power off) and then power on without having to reconfigure
your hard drive type. If you use older hard drives which do not support this feature,
then you must configure the hard drive in the standard method as described above
by the "User" option.
NOTE: After the IDE hard disk drive information has been entered into BIOS, new
IDE hard disk drives must be partitioned (such as with FDISK) and then formatted
before data can be read from and write on. Primary IDE hard disk drives must have
its partition set to active (also possible with FDISK).

Quick Power On Self Test
This field speeds up the Power-On Self Test (POST) routine by skipping retesting a
second, third, and forth time. Setup default setting for this field is Enabled. A
complete test of the system is done on each test.
HDD Sequence SCSI/IDE First (New Feature!)
When using both SCSI and IDE hard disk drives, IDE is always the boot disk using
drive letter C (default setting of IDE). This new feature allows a SCSI hard disk
drive to be the boot disk when set to SCSI. This allows multiple operating systems
to be used on both IDE and SCSI drives or the primary operating system to boot
using a SCSI hard disk drive.
Boot Sequence
This field determines where the system looks first for an operating system. Options
are C,CDROM,A; CDROM,C,A; A,C; C,A The setup default setting is to check first
the hard disk and then the floppy drive; that is, C, A.

delay rate options are available: 250ms, 500ms, 750ms and 1000ms. Setup default
value is 250ms.
Security Option
This field determines when the system prompts for the password. The default setting is System, where the system prompts for the User Password every time you
boot up. The other option is Setup, where the system always boots up, and prompts
for the Supervisor Password only when the Setup utility is called up. You can specify
a password by using the Supervisor Password or User Password option from the
main screen as explained later in this section.
IV. BIOS
(BIOS Features)
PS/2 Mouse Function Control
The default of Auto allows the system to detect a PS/2 Mouse on bootup. If detected, IRQ12 will be used for the PS/2 Mouse. IRQ12 will be reserved for expansion cards if a PS/2 Mouse is not detected. Disabled will reserve IRQ12 for expansion cards and therefore the PS/2 Mouse will not function.
PCI/VGA Palette Snoop
Some display cards that are nonstandard VGA such as graphics accelerators or MPEG
Video Cards may not show colors properly. The setting Enabled should correct this
problem. Otherwise leave this on the setup default setting of Disabled.
OS/2 Onboard Memory > 64M
When using OS/2 operating systems with installed DRAM of greater than 64MB,
you need to Enable this option otherwise leave this on the setup default of Disabled.
......................................................................................................................................
Video BIOS Shadow
This field allows you to change the video BIOS location from ROM to RAM. Relocating to RAM enhances system performance, as information access is faster than
the ROM. Setup default setting is Enabled.
C8000-CBFFF to DC000-DFFFF
These fields are used for shadowing other expansion card ROMs. If you install
other expansion cards with ROMs on them, you will need to know which addresses
the ROMs use to shadow them specifically. Shadowing a ROM reduces the memory
available between 640KB and 1024KB by the amount used for this purpose. Leave

Details of Power Management Setup:
IV. BIOS
(Power Management)
Power Management (User Defined)
This field acts as the master control for the power management modes. There are
four options: Max Saving, Min Saving, Disabled, and User Defined. Max Saving
puts the system into power saving mode after a brief period of system inactivity;
Min Saving is almost the same as Max Saving except that this time the system inactivity period is longer; Disabled disables the power saving features; User Defined
allows you to set power saving options according to your preference.
IMPORTANT: Advanced Power Management (APM) should be installed to
keep the system time updated when the computer enters suspend mode activated by the BIOS Power Management. For DOS environments, you need to
add DEVICE=C:\DOS\POWER.EXE in you CONFIG.SYS. For Windows 3.1x
and Windows 95, you need to install Windows including the APM feature. A
battery and power cord icon labeled "Power" will appear in the "Control Panel."
Choose "Advanced" in the Power Management Field.
Video Off Option (Susp, Stby->Off )
This field determines when to activate the video off feature for monitor power management. The settings are Susp, Stby->Off, Suspend->Off, Always on, and All modes->off.
Video Off Method (V/H SYNC + Blank)
This field defines the video off features. Three options are available: V/H SYNC +
Blank, DPMS, and Blank Only. The first option, which is the default setting, blanks
the screen and turns off vertical and horizontal scanning; DPMS (acronym for Display Power Management System) allows the BIOS to control the video display card
if it supports the DPMS feature; Blank Screen only blanks the screen. Use the latter
for monitors that do not support the “Green” (no power management) feature.
Take note that a screen saver software does not work with this feature. While the

the normal CPU speed is divided by.
PM Timers
This section controls the time-out settings for the Power Management scheme. The
fields included in this section are “HDD Power Down”, which places the hard disk
into its lowest power consumption mode, and the Doze, Standby and Suspend system inactivation modes.
The system automatically “wakes up” from any power saving mode when there is
system activity such as when a key is pressed from the keyboard, or when there is
activity detected from the enabled IRQ channels.
HDD Power Down shuts down any IDE hard disk drives in the system after a period of inactivity. This time period is user-configurable to 1-15 Mins or Disable.
This feature does not affect SCSI hard drives.
IV. BIOS
(Power Management)
The Doze Mode, Standby Mode, and Suspend Mode fields set the period of time
after which each of these modes activate. At Max Saving, these modes activate
sequentially (in the given order) after one minute; at Min Saving after one hour.
PM Events
This section sets the wake-up call of the system. If activity is detected from any
enabled IRQ channels in the left-hand group, the system wakes up from suspended
mode. You can enable power management for IRQs 3 ~ 15 individually in the list at
the right of the screen. The power management feature will work on the enabled
IRQ channels.
Take note that a Microsoft serial mouse or compatible will use either COM1 (IRQ4)
or COM2 (IRQ3), and a PS/2 mouse will use IRQ12. If you know which IRQ your
mouse is using, you can enable the Wake-up Event for that IRQ here and the system
will wake up when you move the mouse or click its button.

IRQ xx Used By ISA
These fields indicate whether or not the displayed IRQ for each field is being used
by a Legacy (non-PnP) ISA card. Two options are available: No/ICU and Yes. The
first option, the default value, indicates either that the displayed IRQ is not used or
an ISA Configuration Utility (ICU) is being used to determine if an ISA card is
using that IRQ. If you install a Legacy ISA card that requires a unique IRQ, and you
are not using an ICU, you must set the field for that IRQ to Yes. For example: If you
install a Legacy ISA card that requires IRQ 10, then set IRQ10 Used By ISA to Yes.

DMA x Used By ISA
These fields indicate whether or not the displayed DMA channel for each field is
being used by a Legacy (non-PnP) ISA card. Available options include: No/ICU
and Yes. The first option, the default setting, indicates either that the displayed
DMA channel is not used or an ICU is being used to determine if an ISA card is
using that channel. If you install a Legacy ISA card that requires a unique DMA
channel, and you are not using an ICU, you must set the field for that channel to Yes.

and allow the DMI to retrieve data from this database. Unlike other BIOS software,
the BIOS on this motherboard uses the same technology implemented for Plug and
Play to allow dynamic real-time updating of DMI information versus creating a new
BIOS image file and requiring the user to update the whole BIOS. This DMI Configuration Utility also allows the system integrator or end user to add additional
information into the MIFD such as serial numbers, housing configurations, and vendor information. Those information not detected by the motherboard BIOS and has
to be manually entered through the DMI Configuration Utility and updated into the
MIFD. This DMI Configuration Utility provides the same reliability as PnP updating and will prevent the refreshing failures associated with updating the entire BIOS.
The DMI Configuration Utility (DMICFG.EXE) must be ran in real mode in order
for the program to run, the base memory must be at least 180K. Memory managers
like HIMEM.SYS (required by windows) must not be installed. You can boot up
from a system diskette without AUTOEXEC.BAT and CONFIG.SYS files, “REM”
HIMEM.SYS in the CONFIG.SYS, or press <F5> during bootup to bypass your
AUTOEXEC.BAT and CONFIG.SYS files.

Troubleshooting Tips
SCSI Device Troubleshooting
Review this checklist if your newly-installed SCSI disk drives, CDROM drives, and
other devices do not seem to work properly:
• Be sure that termination is correctly set for all devices on the SCSI bus, as
•
•
•
•
described in your host adapter documentation.
Be sure there are no hardware conflicts such as devices in your computer trying to use the same interrupts (IRQs) or DMA channels.
Be sure the cables connecting the external and internal SCSI devices and the
host adapter are attached securely. Also be sure the pin-1 orientation is correct
for internal cables. See the host adapter documentation for more information.
Be sure that each SCSI device connected to the host adapter has a unique SCSI
ID.
Be sure CD-ROM drives and other SCSI devices are attached to a power source
and are turned ON.
Windows95/WindowsNT Troubleshooting
What is a miniport driver, and how do I make sure that the miniport driver is
installed correctly?
Miniport drivers are a new kind of 32bit protect mode device driver used by Windows95 and WindowsNT to control host adapters and other kinds of devices. Windows95 and WindowsNT include a set of miniport drivers for various types of SCSI
host adapters. The host adapter miniport driver is automatically installed and configured during Windows95 and WindowsNT installation if your host adapter is already installed. To make sure the driver is installed correctly in systems running
Windows95, open the Control Panel, double-click on System, and click the Device
Manager tab. Then double-click the SCSI Controllers icon; you should see the model
name of the SCSI host adapter(s) installed in your system.
What if there is no SCSI controllers icon under Device Manager, or the model
name of the SCSI chipset does not appear under Device Manager?
If the SCSI controllers icon or your host adapter’s model name do not appear, open
Control Panel and double-click the Add New Hardware icon. Let Windows search
for the host adapter by selecting Yes on the second screen of the Add New Hardware
Wizard.
If Windows does not detect the host adapter, run the Add New Hardware Wizard
again. This time, select No on the second screen of the wizard, then select SCSI
controllers on the next screen. Select the name of your host adapter when it appears.

VI. EZ-SCSI UTILITY
(Troubleshooting)
If the name of your SCSI chipset does not appear, you may be able to find its
miniport driver on the Windows95 CD-ROM. Follow these steps:
1 Place the Windows95 CD-ROM in your CDROM drive and run the Add New
Hardware wizard.
2 Select No on the second screen, and select SCSI controllers on the next screen.
3 Click on the Have Disk button, then click the Browse button.
4 Look in the \drivers\storage directory of the CDROM and select the name of
your SCSI host adapter if it appears.
What if a yellow exclamation point or a red X appears in Device Manager in
front of my host adapter?
This means there is some kind of resource problem. First, see if the names of any
host adapters appear that are not actually installed in your computer. If so, select the
name and click Remove. If a red X appears in front of your host adapter name,
remove all the host adapter references under SCSI Controllers and run Add New
Hardware, as described in the previous question/answer. If a yellow exclamation
point appears in front of your host adapter name, the resources that the driver uses
probably do not match the resources used by the hardware. Double-click the host
adapter name, then click on the Resource tab. Deselect the Use automatic settings
box and edit the resources (Interrupt Request, Direct Memory Access, etc.) so they
match those used by the host adapter. If the problem still remains, there is probably
a hardware resource conflict between the host adapter and other hardware in your
computer. You can fix this by changing the hardware resource settings. (See your
hardware documentation.)
What do I need to do if I want to use another host adapter?
1 Open the Control Panel, double-click on System, and click the Device Manager tab.
2 Double-click the SCSI Controllers icon, select the name of the old host adapter,
and click Remove.
3 Turn OFF the computer and physically remove the currently installed host
adapter.
4 Install the new host adapter according to the instructions in the hardware documentation.
5 Turn the computer ON. If the new host adapter supports Plug and Play, Windows will install and configure it automatically. Otherwise, run Add New Hardware to make sure the new driver is loaded.

(Troubleshooting)
If I am running under Windows95, do I need lines for the Adaptec real mode
ASPI drivers and mscdex in my config.sys and autoexec.bat files?
Usually, you do not need to use these real mode ASPI drivers, because the new
Windows miniport drivers support most SCSI host adapters and SCSI devices. However, you need to load the drivers (including mscdex, if you have a CDROM drive)
if any of the following is true:
• You are running in MSDOS mode
• You are using a scanner or another SCSI device with config.sys- or autoexec.bat•
•
based drivers, such as HP’s sjiix.sys
You have an older model SCSI-1 CDROM drive that Windows95 does not
support
You are using a CD-Recorder drive (however, some newer models of CDRecorder drives can use the embedded Windows miniport drivers)
To install the Adaptec EZSCSI DOS drivers, click the Start button and select Restart the computer in MS-DOS mode. When the DOS prompt appears, follow the
Quick Start instructions for DOS.
My CDROM drive doesn’t work properly under Windows95.
Some older models of SCSI CDROM drives are not compatible with the embedded
Windows95 CDROM driver. You can add support for the CDROM drive by doing
the following:
1 Click the Start button and select Restart the computer in MS-DOS mode.
2 When the DOS prompt appears, follow the Quick Start instructions for DOS.
3 When you are finished running Adaptec EZSCSI for DOS, find the file named
cdtsd.vxd in the windows\system\iosubsys directory and rename it cdtsd.sav.
My CDROM drive shows up as more than one icon under My Computer.
The mapping between mscdex, which runs in real mode, and the Windows95 CDROM
driver does not match. You can correct this in one of two ways:
• Comment out the line that loads mscdex.exe in the autoexec.bat file.
• Change the /L switch on the line that loads mscdex.exe in the autoexec.bat file
so it assigns the CDROM drive the next highest logical drive letter after the
hard disk drives.

(DOS/Win Info.)
Information for DOS/Windows 3.1x Users
The following information may be useful if you install Adaptec EZSCSI on a computer running DOS, Windows 3.1x, or Windows for Workgroups3.1x.
NOTE: The Windows95/WindowsNT Troubleshooting section on page 6 describes a few situations when you may need to use the DOS/Windows3.1x drivers and ASPI managers under Windows95 or WindowsNT.
DOS and Windows3.1x Device Drivers
Device drivers are software programs that enable your computer to communicate
with SCSI devices such as hard disk drives, CDROM drives, and scanners. Each
kind of device requires a different device driver. Adaptec EZSCSI includes several
DOS/Windows3.1x device drivers that are copied to your hard disk during installation. Adaptec EZSCSI adds command lines to your config.sys and autoexec.bat files
to load these device drivers if it finds these kinds of devices on your computer.
To learn more about the Adaptec EZSCSI device drivers, including their command
line option information, see the online Adaptec EZSCSI Online Reference, a Windows Help application.
DOS and Windows3.1x ASPI Managers
ASPI (Advanced SCSI Programming Interface) managers are software programs
that enable the SCSI device drivers, your host adapter, and your SCSI devices to
communicate with each other. ASPI managers are written for a specific operating
system, such as DOS, and a specific family of Adaptec host adapters.
Adaptec EZSCSI includes several ASPI managers for DOS/Windows3.1x. When
you install Adaptec EZSCSI on these operating systems, it detects what kind of host
adapter is installed in your computer and automatically configures your system with
the correct ASPI manager. To learn more about these ASPI managers, including
their command line option information, see the Adaptec EZSCSI Online Reference,
a Windows Help application.

(Formatting)
DOS Formatting Utilities
Adaptec EZSCSI includes several DOS-based formatting utilities:
Low-level Formatter (scsifmt)
Use the DOS-based scsifmt utility for low-level formatting of SCSI hard disk drives,
removable media, Floptical® drives, and magneto-optical drives. You can also use
it to scan a disk device for surface defects before you store data on it.
Run scsifmt from the DOS prompt, not from the Windows MSDOS prompt. Before
you run it, be sure the disk devices you want to format are connected to the host
adapter and that they are powered. Then follow these steps:
1. Change to the directory where scsifmt.exe is located (usually c:\scsi), type
scsifmt at the DOS prompt, and press Enter.
NOTE: If you are formatting a SCSI disk device that supports more than
one LUN (for example, Iomega’s Bernoulli dual multidrive) type scsifmt /
L at the command line.
2. When the first screen appears, read it and press Enter to continue. (Press F1 at
any time to view Help.) Information about your SCSI disk devices appears on
the screen.
3. Use the arrow keys to move the highlight bar to a disk device you want to
format or verify, then press Enter.
4. When the next screen appears, select either Format or Verify (to verify that the
disk is free of surface defects), then press Enter.
WARNING: Back up important data before you format the disk device!
A low-level format erases all data from the disk.
5. If you select Format, confirm that you want to format the disk, then wait while
the disk device is formatted. This may take a long time if the disk is large.
If you select Verify, you can press Esc at any time to stop the verification
process. (This does not damage the disk.) If the utility finds bad blocks on the
disk, it displays information about them. You can reassign the bad block(s) to
prevent data from being stored there.
6. Repeat steps 3, 4, and 5, as needed, to format or verify other disk devices.
When you are finished, press Esc to exit.

(Partitioning)
Formatter and Partitioner (afdisk)
Use the DOS-based afdisk utility to partition and format SCSI hard disk drives,
Floptical drives, and magneto-optical drives. You can also use afdisk to remove
DOS and non-DOS partitions from a disk drive and to format removable media in
standard hard disk format, OS/2 floppy format, or DOS V (Japanese) format.
NOTE: Use afdisk only if the disk device is not controlled by the host adapter
BIOS—that is, if the host adapter does not have a BIOS or if its BIOS is not enabled. If the disk device is controlled by the host adapter BIOS, use the DOS fdisk
utility to partition and format the disk device. (See the MSDOS documentation.)
Run afdisk from the DOS prompt only, not from the Windows MSDOS prompt.
Before you run it, be sure the disk devices you want to format and partition are
connected to the host adapter and that they are powered. Then follow these steps:
1. Change to the directory where afdisk.exe is located (usually c:\scsi), type afdisk
at the DOS prompt, and press Enter.
Information about your SCSI disk devices appears on the screen. (The number
that appears after Target is the device’s SCSI ID.)
2. Use the arrow keys to move the highlight bar to the disk device you want to
partition, then press Enter.
- If the selected disk device is controlled by the host adapter BIOS, you can
view information about it but you cannot partition it with afdisk (Use the DOS
fdisk and format utilities.)
- If the selected disk device is unpartitioned, you must partition it before you
can format it. To do this, follow the instructions on the screen. (Press F1 to see
an explanation of the partitioning options.)
Information about the selected disk device appears in the lower left of the
screen. Disks smaller than 1Gigabyte have 64 heads, 32 sectors per track, and
cylinders equal to the number of MBytes of available capacity. Disks larger
than 1Gigabyte have 255 heads, 63sectors per track, and one cylinder per
8MBytes of available capacity.

(Removable Media)
Removable Media Manager (rmvtool)
Your copy of Adaptec EZSCSI may include the DOS-based rmvtool utility. If you
have this utility, you can use it to lock, unlock, and eject removable media—for
example, a cartridge in a SyQuest removable cartridge drive. You run rmvtool by
entering commands at the DOS prompt. Here are the commands for a removable
drive installed at SCSI ID 5:
• To lock the disk media:
• To unlock the disk media:
• To eject the disk media:
rmvtool/lock/ID=5
rmvtool/unlock/ID=5
rmvtool/eject/ID=5
NOTE: Some devices do not support the Eject command.
If the device is at another SCSI ID, type that number instead of 5. If you are not sure
which device is at which SCSI ID, type rmvtool/? at the DOS prompt and press
Enter. A list of SCSI devices appears. (Devices that support removable media are
marked.)
If your computer has two or more host adapters, you need to add another number to
the command. For example, if you have two host adapters, one of them is host adapter0
and the other is host adapter1. (This information appears when you type the rmvtool/
? command.) So if the removable disk drive is at SCSI ID 3 on host adapter1, you
would enter this command to lock the disk media:
rmvtool/lock/ID=1:3
You can issue rmvtool commands for two or more devices, and you can add the
commands to the autoexec.bat file. If you add this command line to your autoexec.bat
file, rmvtool locks the media in the two devices when the computer boots. This
prevents the disk media from being removed until another command is issued to
unlock it.
